expected declaration, found 'package' #60
Description
facing "expected declaration, found 'package' " error while trying to run https://play.golang.org/p/ZdFpbahgC1 :
// Go's `math/rand` package provides
// [pseudorandom number](http://en.wikipedia.org/wiki/Pseudorandom_number_generator)
// generation.
package main
import "time"
import "fmt"
import "math/rand"
func main() {
// For example, `rand.Intn` returns a random `int` n,
// `0 <= n < 100`.
fmt.Print(rand.Intn(100), ",")
fmt.Print(rand.Intn(100))
fmt.Println()
// `rand.Float64` returns a `float64` `f`,
// `0.0 <= f < 1.0`.
fmt.Println(rand.Float64())
// This can be used to generate random floats in
// other ranges, for example `5.0 <= f' < 10.0`.
fmt.Print((rand.Float64()*5)+5, ",")
fmt.Print((rand.Float64() * 5) + 5)
fmt.Println()
// The default number generator is deterministic, so it'll
// produce the same sequence of numbers each time by default.
// To produce varying sequences, give it a seed that changes.
// Note that this is not safe to use for random numbers you
// intend to be secret, use `crypto/rand` for those.
s1 := rand.NewSource(time.Now().UnixNano())
r1 := rand.New(s1)
// Call the resulting `rand.Rand` just like the
// functions on the `rand` package.
fmt.Print(r1.Intn(100), ",")
fmt.Print(r1.Intn(100))
fmt.Println()
// If you seed a source with the same number, it
// produces the same sequence of random numbers.
s2 := rand.NewSource(42)
r2 := rand.New(s2)
fmt.Print(r2.Intn(100), ",")
fmt.Print(r2.Intn(100))
fmt.Println()
s3 := rand.NewSource(42)
r3 := rand.New(s3)
fmt.Print(r3.Intn(100), ",")
fmt.Print(r3.Intn(100))
}
code runs fine via 'go run' command line, any ideas on how to get around this?
